OOR can be upgraded with HYPSOS Hybrid Power System using our proprietary Ferrum Power Link (FPL) connection, making both units perform to their highest levels. While OOR performs very good right out of the box, it is made to excel above and beyond when used together with HYPSOS. Using the FPL connection means HYPSOS can measure far deeper inside OOR than it can with any other product. Not only does HYPSOS work better in this combination, OOR will also perform even better than it normally does. The truly balanced design of the preamplifier stage coupled with the discrete power amplifier technology in combination with the implementation of highly selected components is elevated to a level of it”s own. 

Ferrum - OOR
OOR will redefine the category of headphone amplifiers. OOR will drive any headphones effortlessly to the max of their potential, while preserving the essence of the music it amplifies. Ultra low distortion, zero fatigue, huge dynamics and unrivaled detail result in ultimate enjoyment. OOR actually makes something that is very difficult to accomplish, seem like the most natural thing on earth.

Ferrum - Hypsos - Advanced power supply
HYPSOS defines a brand new category of a hifi products. It’s not a simple power supply but an audio component of its own – an equally (or even more) important part of a setup as any other. HYPSOS offers a selection of unique features and even accounts for future software improvements – the device is software controlled with as few hardware dependent elements as possible.

The Unique output cable design: two wires delivering the power and two wires providing the feedback to ensure flat voltage at every moment. This technique eliminates the harmful effects of the cable's resistance effectively improving transient response. The current delivery speed at the powered device's input is significantly improved.
